Bug 1334036 - Part 11: Rewrite test_running_on_compositor.html by Web Animation API. Basically, we can pass all tests in test_running_on_compositor.html. However, there are some known issues: 1. Mutation observation is waiting forever. 2. CSS Transitions are all failed. 3. CSS Animations have leaks, but can pass the tests. Besides, there are still many tests failed in layer/style/tests/test_animations_omta.html. MozReview-Commit-ID: ENtpVmHiy40
